Hi, I understand that there is no normative document for a B2BUA but in general as common sense dictates should the B2BUAs that generate multiple outgoing requests on their UAC side for a single incoming request due to parallel forking create unique From-tags or reuse the same From tag in every request (INVITE)? I have concerns over a SBC vendor that requires same From tag (else some overload prevention kicks in) because it looks like re-using From-tag (but having different Via branches of course) might trigger a loop detected response with some endpoints as per https://tools.ietf.org/html/rfc3261#section-8.2.2.2 What is the best practice here?
Thanks, Andrew _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
